All the goals came in the Second Half after a slow first period saw neither side test the goalkeepers.
Dan Sweeney had a header cleared off the line before Juachim Ejimfor was unlucky to see a wonderful strike from range hit the upright.
The Bees were reduced to 10-men shortly before half time when Darnell Smith was shown a straight red for bringing down a Wembley man racing down on goal.
In a nine minute second half spell, the Bees scored four to put the game beyond any doubt.
First, Dan Sparkes fired home a great free kick from the edge of the box. This was followed by Shaq Coulthirst curling into the bottom right from a Martyn Box assist.
Jack Barham got in on the act when he headed home Sparkes’ cross before Sparkes doubled his tally with a low diving header off of an Ephron Mason-Clark cross.
Chances for Mason-Clark and Rio Connell followed as well as a Zaied Sabti free kick which sailed narrowly wide.
Substitute Jermane Heron pulled a goal back in the 89th minute with a great dipping strike over Rihards Matrevics.
